A 1200×720 PNG summarising a Powder Trip: the snow read, the forecast and the stay.

Caching: Cache-Control: public, max-age=300, s-maxage=300, stale-while-revalidate=600, no-transform. Rendered from the live trip row (stays, rates, forecast), which can change every 5 minutes. Never immutable, so browsers, social scrapers and the CDN fetch a fresh render once the window passes. A changing query parameter (e.g. &d=2026-09-15) still forces a fresh render; unknown parameters are ignored.
